Appropriate brake control must satisfy two requirements, shorter stopping distances and maintenance of better wheel tread conditions. This paper introduces an analytical method based on a dynamic model of the relation between adhesion and braking forces from micro slip to gross sliding. The analysis was applied to the actual brake control of electric multiple unit cars braked from the speed of 140 km/h in consideration of the magnitude of sliding speed. Sliding was controlled according to the detected slip level. Consequently, it is generally preferable to utilize the adhesion force in the micro slip region under normal brake action. In emergency brake to make the stopping distance as short as possible, however, it is effective to utilize the adhesion force in the gross sliding region at the expense of wheel tread surfaces deterioration from the viewpoint of safety.
